The plate and the plate of Teflon
Fluoroplastic materials have unique chemical and mechanical properties. Polytetrafluoroethylene resistant to all organic and mineral acids, alkalis, organic solvents, oxidizing agents except melts and solutions of alkali metals, elemental fluorine, and chlorine trifluoride at elevated temperature with the exception of fluorine gas, chlorine trifluoride, solutions and melts of alkali metals.
Teflon sheets are used for the manufacture of sealing, insulating, anti-friction, chemically resistant construction elements used in various industries, including the food industry and medicine as the details of the process equipment (gaskets, seals, bearings, bearings, die, membranes, etc.. ).
Benefits of PTFE:
Good chemical resistance
Low friction
Approved in contact with food
Good dielectric properties

The dielectric properties of the material are not changed to 200 ° C, and the chemical - 300 ° C.
Polytetrafluoroethylene may briefly applied at temperatures up to + 400 ° C, the upper limit is not limited chemical stability loss and reduction of physical and mechanical properties. When heated above + 327 ° C, material is melting, but the polymer does not go into the viscous-flow condition up to the decomposition temperature of + 415 ° C.
These properties make PTFE products from it indispensable in the chemical, electrical industry, instrument making, mechanical engineering, food, medicine, light industry and the garment industry. Teflon physiologically and biologically harmless.
The introduction of various fillers in the fluoroplastic significantly increases wear resistance, hardness, thermal conductivity, mechanical strength, and decreases the tensile strength, elongation at break, modulus of elasticity increases, the compressive strength.
The choice of material - filler depends on the operating conditions of the product (temperature, pressure, working fluid). Production of details of the plates PTFE sheet is manufactured by machining.
